Virulence Profiles of Bacteremic Extended-Spectrum β-Lactamase-Producing Escherichia coli: Association with Epidemiological and Clinical Features
(Public Library of Science, 2012)
There is scarce data about the importance of phylogroups and virulence factors (VF) in bloodstream infections (BSI) caused by extended-spectrum β-lactamase-producing Escherichia coli (ESBLEC). A prospective multicenter ...

Genomewide overexpression screen for fosfomycin resistance in Escherichia coli: Mura confers clinical resistance at low fitness cost
(American Society for Microbiology, 2012-05-01)
To determine whether the overexpression of chromosomal genes can confer fosfomycin resistance, genomewide screening of a complete set of 5,272 plasmid-expressed open reading frames of Escherichia coli (ASKA collection) was ...

Positive Predictive Value of Leeds Acinetobacter Medium for Environmental Surveillance of Acinetobacter baumannii
(American Society of Microbiology, 2011)
Infections caused by Acinetobacter baumannii often occur in outbreaks during which the bacteria are spread through contact with clinical personnel harboring the bacteria and from colonized hospital equipment (2). Environmental ...

Unmanned aircraft systems for studying spatial abundance of ungulates: Relevance to spatial epidemiology
(Public Library of Science, 2014)
Complex ecological and epidemiological systems require multidisciplinary and innovative research. Low cost unmanned aircraft systems (UAS) can provide information on the spatial pattern of hosts' distribution and abundance, ...

Epidemiologic and Clinical Impact of Acinetobacter baumannii Colonization and Infection: A Reappraisal
(Lippincott Williams & Wilkins, 2014)
Acinetobacter baumannii is one of the most important antibiotic-resistant nosocomial bacteria. We investigated changes in the clinical and molecular epidemiology of A. baumannii over a 10-year period. We compared the data ...

The singular properties of photosynthetic cytochrome c 550 from the diatom Phaeodactylum tricornutum suggest new alternative functions
(Wiley-Blackwell, 2019)
Cytochrome c 550 is an extrinsic component in the luminal side of photosystem II (PSII) in cyanobacteria, as well as in eukaryotic algae from the red photosynthetic lineage including, among others, diatoms. We have established ...

Exopolysaccharide Production by Sinorhizobium fredii HH103 Is Repressed by Genistein in a NodD1-Dependent Manner
(Public Library of Science, 2016)
In the rhizobia-legume symbiotic interaction, bacterial surface polysaccharides, such as exopolysaccharide (EPS), lipopolysaccharide (LPS), K-antigen polysaccharide (KPS) or cyclic glucans (CG), appear to play crucial roles ...

Osmotic stress activates nif and fix genes and induces the Rhizobium tropici CIAT 899 Nod factor production via NodD2 by up-regulation of the nodA2 operon and the nodA3 gene
(Public Library of Science, 2019)
The symbiosis between rhizobia and legumes is characterized by a complex molecular dialogue in which the bacterial NodD protein plays a major role due to its capacity to activate the expression of the nodulation genes in ...

AQP1 and AQP4 Contribution to Cerebrospinal Fluid Homeostasis
(MDPI, 2019-02-24)
Aquaporin 1 (AQP1), expressed in epithelial cells of the choroid plexus, and aquaporin 4 (AQP4) present in ependymal cells and glia limitants have been proposed to play a significant role in cerebrospinal fluid (CSF) ...

Bactericidal Effect of Photodynamic Therapy, Alone or in Combination with Mupirocin or Linezolid, on Staphylococcus aureus
(Frontiers Media, 2017)
Antibiotic treatments frequently fail due to the development of antibiotic resistance, underscoring the need for new treatment strategies. Antimicrobial photodynamic therapy (aPDT) could constitute an alternative therapy. ...
